The Intermatic EI210 10/20/30/60 Minute Electronic Countdown Timer provides silent operation in time ranges 10 to 60 minutes. This energy saving timer is designed to replace any standard toggle style wall switch, single or multi-gang, and automatically limits the "ON" time of lighting loads. This compact solid-state design with silent, state-of-the-art technology provides 2-way operation: immediate switch "OFF" or a time-delayed "OFF" after 15 minutes. To restart timer, simply switch to "OFF" for one second then move toggle switch back to TIMER position. A blocking plate, supplied with the timer, may be used to eliminate permanent "ON" mode for timed "ON" use only. The Countdown Timer is also available in Light Almond and White.
